Title: Apparatus for pressurized screening of a fibrous material liquid suspension
Inventor: YOUNG DOUGLAS L G
IPC: D21D5/02
Filed: 1991-08-19
Granted: 1996-08-06
Abstract: An apparatus, for pressurized screening of a fiber/liquid suspension to separate the fibrous fraction into an accepts portion and a rejects portion, has a housing having an inlet with a heavy and large material trap, an accepts outlet, a rejects outlet, and a dilution liquid inlet.  A hollow cylindrical screen having an open top and bottom communicates with the fibrous suspension inlet chamber and the rejects outlet chamber.  Accepts fibers in the suspension pass through apertures in the screen to the accepts chamber and are discharged through the accepts outlet.  Rejects discharge through the rejects chamber.  A rotor having at least four regions, a closed top, and a bottom mounted drive mechanism is coaxially mounted within the screen.  Hydrodynamic pulses are induced in the suspension in the screening region by a pattern of bumps and/or depressions impressed upon the rotor surface.  The fibrous suspension is maintained at a relatively constant consistency within the screening region by the pumping action of the rotor and by providing dilution liquid to counteract thickening of the suspension.  A dynamic bar screening device directs stones and other large objects out of the fluid stream and into an annular trap and also deflocculates the suspension.

Title: Paddlewheel flowmeter assembly
Inventor: PYZIK THOMAS E
IPC: G01F1/06
Filed: 1992-01-06
Granted: 1995-12-19
Abstract: An assembly for accurately and easily positioning and aligning a sensor device relative to a fluid flow stream in a pipe, incorpo-rates a threaded housing which is engageable with a standard  pipe tee-fitting to provide a platform for linearly positioning the sensor relative to the axis of flow.  A sensor unit subassembly is rotatably supported on the platform so that it may be rotated into proper radial alignment with the flow axis while it is supported on the platform at the proper linear position relative to the flow axis. A paddlewheel flowmeter having a single leg supporting the paddlewheel axle in cantilever fashion forms the sensing unit which exploits the improved alignment accuracy of this assembly to avoid build-up of sludge and debris which might affect free rotation of the paddlewheel.   Separate  and independent lock-nuts  fix the housing in position relative to the tee-fitting, and fix the sensor sub-assembly in position relative to the housing.

Title: Common memory switch for routing data signals
Inventor: MUENTER ERNST AUGUST
IPC: H04L12/56
Filed: 1992-01-06
Granted: 1998-05-05
Abstract: In order to handle a synchronous transfer mode (ATM) cells and synchronous transfer mode (STM) words in a single switch, STM words incoming on a channel are accumulated until a desired data block is available and a switch header is then added thereto in order to form an STM switch cell.  The header includes routing information and a flag indicating the switch cell comprises STM words.  In additional, a switch header is added to each ATM cell incoming on a channel in order to form an ATM switch cell. The header added to ATM cells includes routing information and a flag indicating the cell comprises an ATM cell.  The ATM and STM switch cells feed input channels of a common memory switch.  An ATM switch cell from a given incoming channel is stored at a memory address and the memory address input to a queue which is assigned to the outgoing channel indicated by the routing information of the switch header of the cell.  At the same time, an ATM switch cell intended for an outgoing channel corresponding to the given incoming channel is read out of the switch, stripped of its switch header and passed to the outgoing channel.  An STM cell from a given incoming channel is stored at an address indicative of the given incoming channel and, at the same time, a stored STM switch cell from another incoming channel indicated by the routing information of the incoming cell, is read out of the switch.

Title: Evaluation of the extent of wear of articles
Inventor: MATOSSIAN JESSE N
IPC: G01N3/56
Filed: 1992-02-10
Granted: 2000-04-11
Abstract: An article (40), such as a piece of manufacturing tooling, is modified prior to use by treating a portion of its surface (38) to be worn so that the treated surface worn more than a preselected amount has a different appearance than the treated surface worn less than the preselected amount, using a treatment process in which the treated surface is at least as wear resistant as the untreated surface. Tn one approach, the surface (38) is treated by implanting ions to a preselected depth. The ions are chosen so that the substrate has a different color at depths less than the preselected depth than does the substrate at depths greater than the preselected depth. After wear, the treated surface is visually inspected for color variations that indicate wear to more than the preselected depth. The surface treatment can also be accomplished by ion implanting or ion beam mixing a previously deposited surface coating.

Abstract: A phase error integrator (11) for determining  the phase er-ror between a data signal and a clock signal frequency locked to the data signal has a data input and a clock input.  In one em-bodiment the phase error integrator (11) is formed as two func-tional components, namely a phase error detector (20) and an in-tegrator chain (21). The phase error detector (20) sends to the integrator  (21) one of two output signals (NAR, NAL) depend-ing on whether the phase error is positive or negative. The inte-grator chain has a number of outputs (ERR0-ERR13) the first half of which initially have a binary 1 and the second half of which initially have a binary 0.  Depending on which output sig-nal arrives from the phase error detector the binary 1's shift right or the binary 0's shift left.  The integrator may be combined with a delay block (15) connected to the outputs of the  integrator chain (21).  The data signal is fed to the delay block (15) and a delayed data output signal is obtained which is connected to the data input of the phase error integrator (11). The delay block (15) delays the data signal until there is concordance between the phase of the clock and delayed data signals.

Granted: 1999-01-05
Abstract: Novel agents for improving adhesion performance between fibers and resins in fiber reinforced polystyrene composites and synthesizing method thereof and method for improving adhesion performance in fiber reinforced polystyrene composites by using the copolymers are disclosed. The agents are copolymers of styrene and silane coupling agents, and the copolymer can be manufactured by copolymerizing styrene monomer and silane coupling agents in benzene solvent at nitrogen atmosphere by employing azobisisobutyronitrile (AIBN) and the like as an initiator after purifying the reactants and eliminating polymerization inhibitor from the reactants. The typical copolymer is poly(styrene-co-.gamma.-MPS)(.gamma.-MPS means .gamma. -methacryloxypropyltrimethoxysilane) which is manufactured by copolymerizing styrene monomer and .gamma.-MPS. Adhesion performance of the polystyrene fiber composites is improved by hydrolyzing the copolymer in the presence of solvent and applying the copolymer to the surface of the fibers for reinforcing and then immersing the fibers into polystyrene resin composition after drying. Fiberglass materials are most preferably employed as fibers for reinforcing. Adhesion performance between the fibers and matrix resin is substantially improved, resulting in enhanced the strength and endurance of the composite.
